Samples collected during routine fish health disease screening were
submitted to the provincial government's Animal Health Centre lab in
Abbotsford, B.C. The lab detected the virus with qPCR tests and
confirmed it by genetic sequencing. Histopathological results also
confirmed that the fish were affected with the disease caused by the IHN
virus.

On May 18, 2012, the quarantine around the Dixon Bay farm was broken by Tofino filmmaker and anti-salmon farming activist Warren Rudd,
who was collecting video footage on behalf of CHEK TV.

The actions of the activist and Tofino Water Taxi, which
transported him, are now being investigated by the RCMP and by the
Canadian Food Inspection Agency (CFIA).

Mainstream Canada is considering legal action against the parties who violated the quarantine.
